By now in our popular "Mergernomics" series you've learned how to calculate the potential harm from a horizontal merger; but how do you measure the risk from a vertical merger? In this episode, Cornerstone Research's Dr. Craig Malam tells you everything you need to know about "Vertical Math" analysis in merger review - how to calculate it, what it tells you, and when to use it. Hosts Anant Raut and Analysis Group's Emily Cotton use Microsoft's controversial acquisition of video game maker Activision to discuss with Dr. Malam how to assess the risks of total or partial foreclosure from a vertical merger and how to use this analytical tool in relation to other economic tests in this series.
